ISP List

The ISP List is a database of Internet service and other online content providers that will help you get the information you need for your case. For each Internet Service Provider listed, you’ll find the legal contact information and instructions needed to serve subpoenas, court orders, and search warrants.

The ISP List is a law enforcement community effort, meaning that while it may reside on our website, it belongs to us all. If you come across newer information than what we have listed here, please let us know and we’ll update it. If you discover an ISP that we don’t have in the database, let us know and we’ll add it.

We know that getting the information you need from Internet service and other online content providers can be challenging. If you need assistance in this area, let us know through our Assistance & Training Center. We can answer your questions about submitting a legal request and we can help you decipher the results.
